Abstract
The invention discloses a seamless steel tube mill retracting device which comprises a machine base and a trolley sliding rail which is arranged on the machine base. A rolled tube core rod trolley is arranged on the trolley sliding rail and connected with a gantry frame. Oil cylinder bases are arranged on the machine base and on the two sides of the trolley sliding rail. Hydraulic oil cylinders connected with a hydraulic station are arranged on the oil cylinder bases. The drive ends of the hydraulic oil cylinders are connected with the two sides of the gantry frame. The seamless steel tube mill retracting device adopts two sets of hydraulic oil cylinders to carry out driving. The seamless steel tube mill retracting device is stable and reliable in operate, reduces the fault rate, improves the production operation rate and the retracting precision and ensures the milling quality.
